a core electron, is an electron that isn't a valance electron. That means any electron that is not on the outer shell of an atom
Nitrogen is the element located in group 15, period 2. Thus, its electron configuration is 1s2 2s2 2p3. That means that 2 is its valence shell and 1 is its core shell. Therefore, nitrogen has 2 core electrons and 5 valence electrons.
2 core electrons and 8 valence electrons are there in N3- ion.
The electron configuration of helium is: [Xe] 4f15d16s2.
The energy is higher.
The energy is higher.
The electron is an elementary particle. This means that it cannot be broken down further. Therefore, an electron does not have a "core".

You think probable to electron configuration.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
